Description

Technical Field

[0001] This utility model relates to the field of ventilation technology, specifically to a high-efficiency centrifugal ventilation fan for calcium hydroxide. Background Technology

[0002] Calcium hydroxide is a white powdery solid, commonly known as slaked lime or quicklime. It is a very common and essential material in our daily lives, such as construction and road paving. The production of calcium hydroxide generates dust, and these dust particles seriously affect the health of workers. Therefore, ventilation equipment is needed in the factory, with centrifugal fans being widely used due to their powerful and efficient ventilation.

[0003] Currently, centrifugal fans have different outlet directions depending on the model. Common outlets are upward or forward, and the outlet direction is usually fixed, making it inconvenient to adjust the outlet direction according to the needs of the factory for installation and use. Moreover, when centrifugal fans are disassembled and placed, dust will enter the fan from the outlet, which is not only difficult to clean but also affects the service life of the centrifugal fan. There is an urgent need to design a high-efficiency calcium hydroxide centrifugal fan to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency centrifugal fan for calcium hydroxide to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency centrifugal fan for calcium hydroxide includes a base plate. Two fixed frames are mounted on the top of the base plate, and each fixed frame has a slidingly fitted movable frame. A fan body is rotatably fitted between the two movable frames. A support plate is mounted on one side of one of the movable frames, and a motor is mounted on the top of the support plate. A fan shaft is rotatably fitted on one side of the fan body, and a coupling is provided between the motor output end and the fan shaft. An air inlet is provided on one side of the fan body, and an air outlet is provided on the fan body. A filter screen is mounted on one side of the air inlet. A lifting mechanism is provided between the fixed frames and the movable frames. A sealing block corresponding to the air outlet is provided on the top of the base plate. A fixed plate is slidably fitted between the two fixed frames, and a fixing bolt corresponding to the fan body is provided within the fixed plate.

[0007] Furthermore, a flange ring is provided on the air outlet, and multiple mounting holes are provided on the flange ring. Multiple fixing holes corresponding to the multiple mounting holes are provided on the top of the base plate, and the multiple fixing holes are respectively located around the sealing block.

[0008] Furthermore, two reinforcing rods are obliquely mounted on the top of the support plate, and the end of the reinforcing rod away from the support plate is fixedly connected to one side of one of the movable frames.

[0009] Furthermore, multiple connecting plates are installed around the periphery of the fan body. The multiple connecting plates are distributed equidistantly in a circle, and a connecting hole corresponding to the fixing bolt is opened on one side of each connecting plate.

[0010] Furthermore, the fixed frame is U-shaped, the movable frame is inverted U-shaped, and the two sides of the movable frame are slidably engaged within the two ends of the fixed frame. One of the movable frames is provided with a fixing ring, and the air inlet is rotatably engaged within the fixing ring.

[0011] Furthermore, the lifting mechanism includes a threaded rod rotatably engaged with the top of the fixed frame and a threaded cylinder installed at the bottom of the movable frame. The threaded rod and the threaded cylinder are threadedly engaged, and a rotating wheel is installed at the bottom end of the threaded rod.

[0012] In the above technical solution, the beneficial effects of the calcium hydroxide high-efficiency centrifugal fan provided by this utility model are as follows:

[0013] The movable frame allows for adjustment of the height of the movable frame and the main body of the fan by adjusting the lifting mechanism. This allows the main body of the fan to rotate and adjust the orientation of the air outlet, enabling adjustments as needed. This facilitates changing the orientation and height of the air outlet during installation. The sealing block allows the main body of the fan to rotate so that the air outlet faces downwards, aligning with the sealing block. This seals and blocks the air outlet, reducing the possibility of dust entering the main body of the fan from the air outlet during disassembly and placement. Attached Figure Description

An air inlet 9 is provided on one side of the fan body 4, and an air outlet 10 is provided on the fan body 4. A filter screen 11 is installed on one side of the air inlet 9. A lifting mechanism 12 is provided between the fixed frames 2 and the sliding frames 3. A sealing block 13 corresponding to the air outlet 10 is provided on the top of the base plate 1. A fixed plate 14 is slidably fitted between the two fixed frames 2, and a fixing bolt 15 corresponding to the fan body 4 is provided inside the fixed plate 14.

[0023] Reference Figure 1 In this embodiment, a flange ring 16 is provided on the air outlet 10, and multiple mounting holes 17 are provided on the flange ring 16. Multiple fixing holes 18 corresponding to the mounting holes 17 are provided on the top of the base plate 1. The multiple fixing holes 18 are located around the sealing block 13. The flange ring 16 can be used to connect and fix the air outlet 10 to the factory exhaust pipe. When the air outlet 10 corresponds to the sealing block 13, it can be fixed through the fixing holes 18 and the mounting holes 17, so that the air outlet 10 and the sealing block 13 are sealed together.

[0024] Reference Figure 2In this embodiment, two reinforcing rods 19 are obliquely installed on the top of the support plate 5. The end of the reinforcing rod 19 away from the support plate 5 is fixedly connected to one side of one of the movable frames 3. The reinforcing rods 19 can support and fix the support plate 5, thereby strengthening the connection between the support plate 5 and the movable frame 3.

[0025] Reference Figure 3 In this embodiment, multiple connecting plates 20 are installed around the periphery of the fan body 4. The multiple connecting plates 20 are distributed equidistantly in a circle, and a connecting hole 21 corresponding to the fixing bolt 15 is opened on one side of the connecting plate 20. Through the connecting plate 20, the connecting plate 20 can be fitted to the fixing plate 14. The fixing bolt 15 is inserted into the connecting hole 21 to connect the fixing plate 14 and the connecting plate 20, thereby fixing the fan body 4. When the height of the fan body 4 is adjusted, the connecting plate 20 will drive the fixing plate 14, so that the fixing plate 14 rises or falls along the fixing frame 2.

[0026] Reference Figure 4 In this embodiment, the fixed frame 2 is U-shaped, and the movable frame 3 is inverted U-shaped.

[0028] Working Principle: In use, first move the device to the desired location. Adjust the fan body 4 according to the position of the factory's air outlet duct, causing the fan body 4 to adjust the air outlet 10. Adjust the orientation of the air outlet 10 to upward, forward, or other inclined directions. After adjustment, use the fixing bolts 15 to secure the fan body 4. Then, activate the lifting mechanism 12, causing it to move the movable frame 3. The movable frame 3 will then raise or lower the fan body 4, aligning the air outlet 10 with the factory's air outlet duct. Connect the air outlet 10 to the factory air outlet pipe. Starting the motor 6 will drive the fan shaft 7 to rotate, causing the fan shaft 7 to drive the blades inside the fan body 4 for ventilation. The air inlet 9 will draw in air, which will be filtered by the filter screen 11 and then discharged through the air outlet 10 to complete the ventilation work. When the device is no longer needed, it can be removed. The fan body 4 can be rotated so that the air outlet 10 faces downward. At this time, the air outlet 10 will correspond to the sealing block 13. Moving the fan body 4 downward will allow the sealing block 13 to seal the air outlet 10. Then the device can be stored.
